[0004] --Original application title: A method and apparatus for a user equipment and base station used in wireless communication Technical Field

[0005] This application relates to a wireless signal transmission scheme in a wireless communication system, and in particular to a method and apparatus for multi-antenna transmission. Background Technology

[0006] Massive MIMO (Multi-Input Multi-Output) has become a research hotspot in next-generation mobile communications. In massive MIMO, multiple antennas are beamformed to form a narrow beam pointing in a specific direction to improve communication quality.

[0007] During the 3GPP (3rd Generation Partner Project) New Radio discussions, some companies proposed that user equipment should measure the serving beam during communication. When the quality of the serving beam is found to be poor, the uplink physical layer control channel is used by the user equipment to send a beam recovery request carrying candidate beam information to the base station, and the base station then replaces the serving beam. Summary of the Invention

[0008] The inventors discovered through research that the information carrying capacity of channels used to send beam recovery requests is limited, especially for PRACH (Physical Random Access Channel) based channels. Therefore, how to use limited overhead to carry candidate beam information on channels used to send beam recovery requests is an urgent problem to be solved.

[0009] To address the aforementioned problems, this application provides a solution. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other. For example, the embodiments and features described in these embodiments of the user equipment can be applied to a base station, and vice versa.

[0010] This application discloses a method for a user equipment used in wireless communication, which sequentially performs the following steps:

[0011] - Transmit the first wireless signal on the first channel.

[0012] - Monitor the second wireless signal within the first time window.

[0013] Wherein, if the first channel is a first-type channel, a first bit block is used to generate the first wireless signal, and the value of the first bit block is used to determine the multi-antenna-dependent transmission for the second wireless signal; if the first channel is a second-type channel, a second feature sequence is used to generate the first wireless signal, the second feature sequence being one of Q2 candidate sequences, and at least one of {the index of the second feature sequence in the Q2 candidate sequences, the time-domain resources occupied by the second feature sequence, and the frequency-domain resources occupied by the second feature sequence} is used to determine the multi-antenna-dependent transmission for the second wireless signal; the transmission of the first wireless signal is determined by the user equipment itself. Q2 is a positive integer greater than 1.

[0014] As an example, the advantage of the above method is that both types of channels can be used to send beam recovery requests, thus increasing the flexibility of system scheduling and reducing the latency of reporting beam recovery requests.

[0015] As one embodiment, the first wireless signal is used to trigger the transmission of the second wireless signal.

[0016] As a sub-example, the multi-antenna-dependent transmission for the second wireless signal refers to the transmission beam used to transmit the second wireless signal.

[0017] As a sub-example, the multi-antenna-related transmission for the second wireless signal refers to CSI-RS (Channel State Information Reference Signal) spatially correlated with the DMRS (Demodulation Reference Signal) used to demodulate the second wireless signal.

[0018] As a sub-example, the multi-antenna-related transmission for the second wireless signal refers to the SS (Synchronization Signal) spatially associated with the DMRS used to demodulate the second wireless signal.

[0019] As an example, the first type of channel is PUCCH (Physical Uplink Control Channel).

[0020] As an example, the first bit block is part of a UCI (Uplink Control Information), which is encoded by the uplink control channel to obtain the first radio signal.

[0021] As an example, the first bit block is a UCI, which is encoded by the uplink control channel to obtain the first radio signal.

[0022] As an example, the first type of channel is PUSCH (Physical Uplink Shared Channel).

[0023] As an example, the first bit block is a data block.

[0024] As an example, the first bit block is encoded and modulated through the uplink data transmission channel to obtain the first wireless signal.

[0025] As an example, the first bit block is used to determine from P1 transmit beams the transmit beam used to transmit the second wireless signal, where P1 is a positive integer greater than 1.

[0026] As one embodiment, the first bit block includes the index of the transmit beam used to transmit the second wireless signal among the P1 transmit beams.

[0027] As an example, the first bit block is used to determine a reference signal from P2 reference signals that is related to the reference signal space used to demodulate the second wireless signal, where P2 is a positive integer greater than 1.

[0028] As one embodiment, the first bit block includes an index of the reference signal in the P2 reference signals associated with the reference signal space used for demodulating the second wireless signal.

[0029] As an example, the spatial correlation refers to the spatial QCL (Quasi Co-Located).

[0030] As an example, the second type of channel is PRACH (Physical Random Access Channel).

[0031] As an example, the second type of channel is a channel used to transmit feature sequences.

[0032] As an example, any one of the Q2 candidate sequences is a Zadoff-Chu sequence.

[0033] As an example, the Q2 candidate sequences are Zadoff-Chu sequences generated from the same root, each corresponding to a different cyclic shift.

[0034] As an example, the second feature sequence is obtained by adding a CP (Cyclic Prefix) to obtain the first wireless signal.

[0035] As an example, the second feature sequence is used to obtain the first wireless signal after power adjustment.

[0036] As an example, any one of the Q2 candidate sequences is a pseudo-random sequence.

[0037] As an example, at least one of {the index of the second feature sequence in the Q2 candidate sequences, the time domain resources occupied by the second feature sequence, and the frequency domain resources occupied by the second feature sequence} is used to determine the transmission beam used to transmit the second wireless signal from P1 transmission beams, where P1 is a positive integer greater than 1.

[0038] As an example, the index of the second feature sequence in the Q2 candidate sequences is the index of the transmission beam used to transmit the second wireless signal in the P1 transmission beams.

[0039] As an example, the P1 transmit beams are divided into N1 transmit beam groups, and the index of the second feature sequence in the Q2 candidate sequences is used to indicate the first transmit beam group. The first transmit beam group is one of the N1 transmit beam groups, and the transmit beam used to transmit the second wireless signal is one of the beams in the first transmit beam group.

[0040] As an example, the index of the second feature sequence in the Q2 candidate sequences and the index of the time-frequency resources occupied by the second feature sequence in the P3 candidate time-frequency resources are combined to generate the index of the transmission beam used to transmit the second wireless signal in the P1 transmission beams, where P3 is a positive integer greater than 1.

[0041] As an example, the first index value is the index value of the transmitting beam used to transmit the second wireless signal in the P1 transmitting beams, the index of the time-frequency resources occupied by the second feature sequence in the P3 candidate time-frequency resources is the high-order bit of the first index value, and the index of the second feature sequence in the Q2 candidate sequences is the low-order bit of the first index value.

[0042] As one embodiment, the P1 transmission beams are divided into N1 transmission beam groups. The time-frequency resources occupied by the second feature sequence are used to indicate the first transmission beam group, which is one of the N1 transmission beam groups. The index of the second feature sequence in the Q2 candidate sequences is used to indicate the index of the transmission beam used to transmit the second wireless signal in the first transmission beam group. N1 is a positive integer greater than 1.

[0043] As an example, the transmit beams in the transmit beam group can be simultaneously received by the user equipment.

[0044] As an example, at least one of {the index of the second feature sequence in the Q2 candidate sequences, the time domain resources occupied by the second feature sequence, and the frequency domain resources occupied by the second feature sequence} is used to determine a reference signal related to the reference signal space for demodulating the second radio signal from P2 reference signals, where P2 is a positive integer greater than 1.

[0045] As an example, the index of the second feature sequence in the Q2 candidate sequences is the index of the reference signal associated with the reference signal space used to demodulate the second wireless signal in the P2 reference signals.

[0046] As an example, the index of the second feature sequence in the Q2 candidate sequences and the index of the time-frequency resources occupied by the second feature sequence in the P3 candidate time-frequency resources are combined to generate the index of the reference signal related to the reference signal space used for demodulating the second wireless signal in the P2 reference signals, where P3 is a positive integer greater than 1.

[0047] As an example, the first index value is the index value of the reference signal associated with the reference signal space used to demodulate the second wireless signal in the P2 reference signals, the index of the time-frequency resources occupied by the second feature sequence in the P3 candidate time-frequency resources is the high-order bit of the first index value, and the index of the second feature sequence in the Q2 candidate sequences is the low-order bit of the first index value.

[0048] As an example, the P2 reference signals are divided into N1 reference signal groups, and the time-frequency resources occupied by the second feature sequence are used to indicate the first reference signal group, which is one of the N1 reference signal groups. The index of the second feature sequence in the Q2 candidate sequences is used to indicate the index of the reference signal related to the reference signal space used for demodulating the second radio signal in the first reference signal group, where N1 is a positive integer greater than 1.

[0049] As an example, reference signals spatially related to the reference signals in the reference signal group can be simultaneously received by the user equipment.

[0050] As an example, the second wireless signal is transmitted on the PDCCH (Physical Downlink Control Channel).

[0051] As an example, DCI (Downlink Control Information) is used to generate the second radio signal.

[0052] As an example, the user equipment's measurement of the PDCCH (Physical Downlink Control Channel) is used to trigger the transmission of the first wireless signal, and the result of the measurement is below a target threshold.

[0053] As an example, the target threshold is configured by the base station.

[0054] As an example, the target threshold is configured by default.

[0055] As an example, the user equipment's measurement of PDSCH (Physical Downlink Shared Channel) is used to trigger the transmission of the first wireless signal, and the result of the measurement is below a target threshold.

[0056] As an example, the monitoring refers to blind decoding of the second wireless signal.

[0058] As an example, the first time window is configured by default.

[0059] As one example, the first time window is configured by the base station.

[0060] As an example, the number of bits in the first bit block is Q1, where Q2 is less than 2 raised to the power of Q1, and Q1 is a positive integer.

[0061] As one embodiment, the first type of channel and the second type of channel are respectively in the first time resource pool and the second time resource pool, which are two time resource pools orthogonal in the time domain.

[0062] As an example, the first type of channel is PUCCH, and the second type of channel is on the time domain resources where PRACH (Physical Random Access Channel) is located.

[0063] As an example, if the first channel is a first-class channel, the first information is transmitted once on the first channel.

[0064] As an example, if the first channel is a second type of channel, the first information is repeatedly transmitted on the first channel.

[0065] As an example, if the first channel is a second type of channel, different transmission beams are used to repeatedly transmit the first information on the first channel.

[0066] According to one aspect of this application, if the first channel is a first type channel, the first wireless signal is used to determine a reference signal configuration from M1 reference signal configurations; if the first channel is a second type channel, the first wireless signal is used to determine a reference signal configuration from M2 reference signal configurations; wherein M1 and M2 are positive integers greater than 1, and M2 is less than M1; the reference signal configuration is used to determine the time-frequency resources occupied by a positive integer number of reference signal ports.

[0067] As an example, the advantage of the above method is that it flexibly sets the feedback mechanism according to the channel type, increases the adaptability of the feedback mechanism to the channel type, and saves the overhead of feeding back reference signal configuration information on a second type channel.

[0068] As an example, the reference signal configuration is a CSI-RS (Channel State Information Reference Signal) resource configuration.

[0069] As an example, the reference signal configuration is an SS (Synchronization Signal) resource configuration.

[0070] As an example, the M2 reference signal configurations are a subset of the M1 reference signal configurations.

[0071] As an example, the M2 reference signal configuration is a CSI-RS resource configuration, and the M1 reference signal configuration is an SS resource configuration.

[0072] As one embodiment, the M2 reference signal configurations are used to determine the M2 CSI-RS groups, and the M1 reference signal configurations are used to determine the M1 SS groups.

[0073] As an example, the CSI-RS group includes multiple CSI-RS.

[0074] As an example, the CSI-RS group includes only one CSI-RS.

[0075] As an example, the SS group includes multiple SSs.

[0076] As an example, the SS group includes only 1 SS.

[0077] As an example, the number of bits in the first bit block is Q1, and M1 is less than 2 raised to the power of Q1.

[0078] As a sub-example of the above embodiment, M2 is smaller than Q2.

[0079] As an example, the number of bits in the first bit block is Q1, and M1 is equal to 2 raised to the power of Q1.

[0080] As a sub-example of the above embodiment, M2 is equal to Q2.

[0082] As an example, the reference signal configuration implicitly indicates the time-frequency resources occupied by a positive integer number of reference signal ports.

[0083] According to one aspect of this application, the first wireless signal is used to determine a reference signal configuration group from M3 reference signal configuration groups, the reference signal configuration group including a plurality of reference signal configurations, the reference signal configuration being used to determine the time-frequency resources occupied by a positive integer number of reference signal ports, wherein M3 is a positive integer.

[0086] As an example, the N1 reference signals are configured to correspond to N1 transmission beams.

[0087] As one embodiment, multiple reference signal configurations in the first reference signal configuration group are used to determine the transmission beam used to transmit the second wireless signal.

[0088] As one embodiment, multiple transmit beams corresponding to the first reference signal configuration group are simultaneously used to transmit the second wireless signal.

[0089] As one embodiment, the multiple transmit beams corresponding to the first reference signal configuration group are used in turn in the time domain to transmit the second wireless signal.

[0091] As an example, the M3 reference signal configuration groups are configured by the base station.

[0092] As an example, the M3 reference signal configuration groups are configured by default.

[0093] As an example, the M3 reference signal configuration groups are negotiated between the user equipment and the base station before the user equipment transmits the first wireless signal.

[0094] As an example, the user equipment transmits a third wireless signal before transmitting the first wireless signal. The third wireless signal is used to determine K reference signal configurations from N reference signal configurations, where N is a positive integer and K is a positive integer less than N. The K reference signal configurations are divided into M3 reference signal configuration groups.

[0095] As an example, the user equipment divides the K reference signal configurations into the M3 reference signal configuration groups and notifies the base station.

[0096] As an example, the base station divides the K reference signal configurations into the M3 reference signal configuration groups and notifies the user equipment.

[0097] According to one aspect of this application, a reference signal configuration group is used to determine a plurality of first-class reference signals, and two second-class reference signals spatially related to any two of the plurality of first-class reference signals can be simultaneously received by the user equipment, wherein the first-class reference signals and the second-class reference signals are two types of reference signals with different functions.

[0098] As an example, the advantages of the above method are that it saves feedback overhead, facilitates flexible system scheduling, and makes it easier for the user equipment to receive the second wireless signal.

[0099] As an example, the first type of reference signal is CSI-RS, and the second type of reference signal is DMRS (Demodulation Reference Signal).

[0100] As an example, the first type of reference signal is SS, and the second type of reference signal is DMRS (Demodulation Reference Signal).

[0101] As one embodiment, the user equipment transmits a third wireless signal before transmitting the first wireless signal. This third wireless signal is used to determine K reference signal configurations from N reference signal configurations, where N is a positive integer and K is a positive integer less than N. The user equipment then divides the K reference signal configurations into M3 reference signal configuration groups. The user equipment notifies the base station of this division of the K reference signal configurations.

[0102] As one embodiment, the user equipment uses different antenna panels or the same receiving beam to receive the transmitting beams corresponding to the plurality of first-type reference signals respectively.

[0103] As one embodiment, one of the antenna panels is connected to a radio frequency circuit.

M4 and M5 are both positive integers greater than 1, and M5 is less than M4.

[0105] As an example, the advantage of the above method is that it uses two types of channels with different load capacities to transmit user equipment requests in different ways, thereby saving feedback overhead and improving transmission efficiency.

[0106] As an example, the number of bits in the first bit block is Q1, and M4 is less than 2 raised to the power of Q1.

[0107] As a sub-implementation of the above embodiment, M5 is smaller than Q2.

Figure 2This diagram illustrates the network architecture 200 of LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), and future 5G systems. The LTE network architecture 200 can be referred to as EPS (Evolved Packet System) 200. EPS 200 may include one or more UEs (User Equipment) 201, E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, EPC (Evolved Packet Core) 210, HSS (Home Subscriber Server) 220, and Internet services 230.

[0217] Example 3

[0218] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and control plane. Figure 3The radio protocol architecture for the UE and eNB is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the UE and eNB via PHY301. In the user plane, L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the eNB on the network side. Although not illustrated, the UE may have several upper layers above L2 layer 305, including a network layer (e.g., IP layer) terminating at the P-GW213 on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.). PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides header compression for upper-layer packets to reduce radio transmission overhead, provides security through packet encryption, and provides handover support between eNBs to UEs. RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among UEs. MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for UEs and eNBs is largely the same for physical layer 301 and L2 layer 305, but header compression functionality for the control plane is absent. The control plane also includes the RRC (Radio Resource Control) sublayer 306 in layer 3 (L3). RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the eNB and the UE.

[0226] Example 4

[0227] Example 4 illustrates a schematic diagram of the evolved node and the UE, as shown in the attached diagram. Figure 4 As shown.

[0228] Appendix Figure 4This is a block diagram of the eNB 410 communicating with UE 450 in the access network. In the downlink (DL), upper-layer packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to UE 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to UE 450. The transmit processor 416 implements various signal processing functions for L1 layer (i.e., physical layer). Signal processing functions include decoding and interleaving to facilitate forward error correction (FEC) at UE450 and mapping to signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). The decoded and modulated symbols are then split into parallel streams. Each stream is then mapped to a multicarrier subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently combined using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multicarrier streams are spatially pre-decoded to generate multiple spatial streams. Each spatial stream is then provided to a different antenna 420 via transmitter 418. Each transmitter 418 modulates an RF carrier with the corresponding spatial stream for transmission. At UE450, each receiver 454 receives the signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and provides the information to the receiver processor 456. The receiver processor 456 implements various signal processing functions of the L1 layer. The receiver processor 456 performs spatial processing on the information to recover any spatial stream destined for the UE 450. If multiple spatial streams are destined for the UE 450, they can be combined by the receiver processor 456 into a single multicarrier symbol stream. The receiver processor 456 then uses a Fast Fourier Transform (FFT) to transform the multicarrier symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate multicarrier symbol stream for each subcarrier of the multicarrier signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the most likely signal clustering points transmitted by the eNB 410 and generating soft decisions. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by the eNB 410 on the physical channel. The data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the L2 layer. The controller / processor may be associated with memory 460, which stores program code and data. Memory 460 may be referred to as computer-readable media.In the DL (Layered Transmission), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above the L2 layer. Various control signals can also be provided to the L3 layer for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation. In the UL (Uplink), a data source 467 is used to provide upper-layer packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the functionality described in the DL transmission combined with the eNB410, the controller / processor 459 implements the L2 layer for the user plane and control plane by providing header compression, encryption, packet segmentation and reordering, and multiplexing between the logical and transport channels through radio resource allocation based on the eNB410. The controller / processor 459 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the eNB 410. The transmit processor 468 selects appropriate encoding and modulation schemes and facilitates spatial processing. The spatial stream generated by the transmit processor 468 is provided to different antennas 452 via individual transmitters 454. Each transmitter 454 modulates an RF carrier with the corresponding spatial stream used for transmission. UL transmission is processed at the eNB 410 in a manner similar to that described in conjunction with the receiver functionality at the UE 450. Each receiver 418 receives signals through its corresponding antenna 420. Each receiver 418 recovers the information modulated onto the RF carrier and provides the information to the receive processor 470. The receive processor 470 may implement the L1 layer. The controller / processor 475 implements the L2 layer. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as computer-readable media. In the UL, the controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer packets from the UE 450. Upper-layer packets from the controller / processor 475 are then provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

(Attached) Figure 5 In the diagram, base station N1 is the sustaining base station for the serving cell of UE U2. The steps marked by boxes F0 and F1 in the diagram are optional.

[0254] Without conflict, the above sub-examples 1-6 can be combined arbitrarily.

[0270] Example 8

[0271] Example 8 illustrates using the first wireless signal to send a beam recovery request, as shown in the attached diagram. Figure 8 As shown.

[0272] In Example 8, the base station and the UE perform the following operations in sequence:

[0273] - The base station sends a first signaling message to the UE, which is used by the UE to determine the time and frequency resources that the beam recovery request can occupy, including the time and frequency resource pool where the PUCCH used to send the beam recovery request is located, and the time and frequency resources and preamble resources of the PRACH used to send the beam recovery request.

[0274] - The base station sends a target radio signal to the UE. The target radio signal is a reference signal used by the UE to perform channel measurement on the PDCCH (Physical Downlink Control Channel). The result of the channel measurement is lower than the target threshold.

[0275] - An event where the channel measurement result falls below a target threshold triggers the UE to send a first beam recovery request on a PUCCH.
